T0 /LZZ whom t may concern:

Be it known that I, ANTON HAoKENBRooH, a resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Cabinet-Heads for Sewing-Machines, of which the following, when taken in connection with the drawings accompanying and forming a part hereof, is a full and complete description, suflicient to enable those skilled in theart to which it pertains to understand, make, and use the same.

This invention relates to what are known in the art as drop cabinet-heads for sewingmachines-that is, sewing-machine cabinetheads which may be placed on iron legs or on a wooden desk-like structure-such cabinethead having a table provided with an aperture therein and having a hinged leaf-top which may be turned to one side of the table, thereby automatically bringing a base-board on which a sewing-machine is secured into position filling the aperture in the table, at which time the sewing-machine is in an operative position; and the object of this invention is to obtain a cabinet-head for a sewingmachine wherein the hinged leaf-top can be easily turned from its position over the table of the head into a position to one side thereof, and thereby automatically raise the sewing-machine base-board, together with the sewing-machine thereon, out from a dropped position into position in the aperture of the top of the table with the sewing-machine in operative place and to obtain a cabinet-head of the kind described wherein the resistance to such turning of the top leaf will be substantially uniform, to obtain a cabinet-head wherein when the top leaf thereof is closed over the table-top and the base-board of the sewing-machine, together with the sewingmachine thereon,fis down such sewing-machine will be inclosed in a substantially dustproof receptacle and when such top leaf is turned to one side,or open,the sewing-machine base-board, together with the portion of the casing of the dust-proof receptacle which would otherwise be an obstruction to the legs of the person operating the sewing-machine, are both automatically raised (at the same time) to permit free movement of the legs of the operator of the machine.

A further object of this invention is to obtain a cabinet-head for sewing-machines of the kind described wherein when the sewingmachine base-board is raised by the turning to one side of the top leaf, as described, the forward edge of the sewing-machine baseboard will be rigidly held in place, so that the sewing-machine may be operated without vibration or movement thereof to any appreciable extent.

The manner in which I accomplish the several objects sought by me is embodied in the construction illustrated in the drawings referred to, in which- Figure l is a longitudinal vertical sectional view of a cabinet-head for sewing-machines with an apparatus embodying the invention attached thereto and shown in rear elevation, the sewing-machine base-board of the apparatus being raised into a horizontal position and the several parts of the apparatus in proper relation thereto. Fig. Qis a longitudinal vertical s'ectional View of a cabinet-head for sewing-machines having an apparatus embodying this invention attached thereto, showing a rear elevation of such apparatus with the sewingmachine base-board down, the top leaf closed, and the remaining parts of the apparatus in proper relation thereto; and Fig. 3 is a lateral vertical sectional view of a cabinet-head for sewing machine having an apparatus embodying this invention attached thereto, with the sewing-machine base-board in a raised position, with the several parts of the apparatus shown in full lines properly related thereto and such machine base-board and the remaining parts of such apparatus indicated by broken lines in a dropped position.

A reference-letter applied to indicate a given part is retained and applied to such part throughout the several figures of the drawings wherever the same appears.

X X are the legs of the cabinet-head.

A is the table of the cabinet-head and is provided with aperture a therein.

a' is a vertical back board to table A and is shown in Fig. 3 of the drawings. Such back board a is removed from its position in Figs.

' l and 2 to expose to view the operative parts of the apparatus.

B is a raised portion to the table A, usually obtained by securing' strips provided with molded edges around the aperture a on the upper surface of the table A. Aperture b is thus obtained, such aperture b corresponding with aperture a.

are hinges, Figs. 1 and 2. One leaf of the respective hinges 7; is attached. to the raised portion B of the table-top, and the other leaf of such hinges is attached to the top leaf C.

D is the sewing-machine base-board of the apparatus.

Z (Z are pivotal hinges by means of which sewing-machine base-board D is attached adjacent to one of the edges thereof to the tabletop in proper place to be turned up through the aperture a into a substantially horizontal position in aperture d is a leaf attached by pivotal hinges Z2 Z2 to the forward edge of the machine base-board D. The machine base-board D, together with the leaf d', substantially lills the aperture when such machine base-board and leaf are in a horizontal position, as illustrated in Figs. l and 3 of the drawings.

Eis a iiexible cord or chain attached at one end, as bya pin or bolt e, to the table-top and at the other end, as by a pin or bolt e', to the top leaf C.

F f are respectively wheels over the periphery of which the chain or iiexible cord E extends.

G is a wheel rotatably mounted in frame g to vtravel on the curved track Gr'. Frame g is secured to the under surface of the machine base-board D, as by the bolts or screws g g', Fig. 3.

The curved tracks Gr G are attached at one end thereof respectively by means of hinges g2 g2 to the under surface of the table-top A. (See Fig. 3.)

H is a bar attached at one end to the free end of one of the curved tracks G G and at the other end attached to the free end of the other one of such tracks. Wheel F is rotatably mounted in bar H, as by axle f.

G2 is a prolongation of curved track G. The forward end or edge of the hinged leaf d rests on the track G' when the base-board D is down in the position illustrated in Fig. 2 of the drawings and indicated by broken lines in Fig. 3, and when such base-board D and loose leaf el are being' raised into a horizontal position such forward edge of the leaf d slides or travels along on the track Gr' until such forward edge reaches the prolongation G2 of such track, after which it travels on such prolongation of the track and is thereby guided into the position illustrated in Fig. 3 of the drawings, where it forms a horizontal extension of the machine base-board D and when in connection with such machine base-board completely filling the aperture b.

I is a panel which is secured at its ends in tracks G' l.

The operation of this machine is as follows: When the top leaf C is turned on hinges from the position in which such top leaf is illustrated in Fig. 2 of the drawings into the position illustrated in Fig. 1 of the drawings, the chain or flexible cord E is thereby drawn over the roller f and around the roller F, thereby raising the bar H and the free ends of the tracks G G, which are attached to the ends of such bar. As the track Gr is raised the roller G is forced to travel along such track from the position thereof indicated by broken lines in Fig. 3 of the drawings into substantially the position thereof illustrated by full lines in such Fig. 3,at which time the machine base-board D is in a substantially horizontal position. As the machine base-board D is thus raised from the position thereof indicated by broken lines in Fig. 3 into the position illustrated by full lines in such Fig. 3 the leaf d' is forced ahead of such machine base-board, the forward edge of such leaf d resting, as described, on the track Gr and on track G2, so that at about the time the inachine base-board D is in a horizontal position such leaf ci will also be in a horizontal position. The panel I, forming the front and under side of the receptacle into which the machine base -board D and loose leaf d' are dropped by closing the top leaf C from the position thereof illustrated in Fig. l of the drawings into the position illustrated in Fig. 2 of the drawings, is raised and lowered with the raising and lowering of the tracks G G, and thus the receptacle named is varied in size by the opening and closing of the top leaf C, such receptacle being sufliciently large when the base-board D is down to contain such baseboard and a sewing-machine attached thereto and being so small when the base-board D is in a horizontal position that the forward and under side thereof (formed by panel l) is out of the way of the legs of a person sitting at the cabinet and operating the treadle of such sewing-machine. A sewing-machine being' attached to this base-board in the same manner as sewing-machines are attached to the baseboard of drop-head cabinets as heretofore made, I have not considered it necessary to illustrate a sewingmachine in the drawings.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a cabinet-head for sewing-machines, the combination of a table provided with an aperture therethrough, a machine base-board pivotally attached to the table, a leaf pivotally attached to the forward edge of the machine base-board and tracks underneath the table pivotally connected at one end thereof, respectively, to the table, such tracks and IOO IIS

pivotally-attached leaf related so that when the machine base-board is in a horizontal plane the forward edge of such leaf rests on the tracks and the leaf is maintained in a horizontal plane thereby; substantially as described.

2. In a cabinet-head for sewing-machines, the combination of a table provided with an aperture therethrough, a leai` above the table, hinges, to attach one edge of the leaf to the table, tracks below the table, a panel between the tracks to move therewith, hinges to attach one end of the tracks to the table, a bar attached to the end of the tracks which are not hinged to the table, a roller rotatably mounted on such bar, la liexible chain or cord eX- tending under the roller, such ieXible connection attached at one end to the table and at the other end to the top leaf, a machine base-board pivotally attached to the table, and rollers rotatably mounted on the under side of the base-board to travel on the tracks; substantially as described.
